按照积极兼容原则，围绕各自职责，中国各级政府有关部门依据《国家核应急预案》明确的任务，分别建立并加强可服务保障核应急的能力体系。

　　按照国家、相关省（区、市）和各核设施营运单位制定的核应急预案，在国家核应急体制机制框架下，各级各类核应急力量统一调配、联动使用，共同承担核事故应急处置任务。

　　五、核事故应对处置主要措施

In accordance with the principle of versatile compatibility and based on their respective duties and responsibilities, government departments at different levels in China have established and reinforced their respective capability systems to serve and safeguard nuclear emergency response activities commensurate with the tasks established under the National Nuclear Emergency Plan.

In accordance with the nuclear emergency response plans worked out by the national and provincial (regional and municipal) authorities and the operators of nuclear installations and within the institutional framework of the national nuclear emergency response system, various levels and categories of nuclear emergency response forces ensure unified deployment and interactive mobilization to jointly undertake tasks associated with nuclear accident emergency situations.

V. Main Measures to Cope with Nuclear Accidents

　　中国参照国际先进标准，汲取国际成熟经验，结合国情和核能发展实际，制定了控制、缓解、应对核事故的工作措施。

　　实施纵深防御。设置五道防线，前移核应急关口，多重屏障强化核电安全，防止事故与减轻事故后果。一是保证设计、制造、建造、运行等质量，预防偏离正常运行。二是严格执行运行规程，遵守运行技术规范，使机组运行在限定的安全区间以内，及时检测和纠正偏差，对非正常运行加以控制，防止演变为事故。三是如果偏差未能及时纠正，发生设计基准事故时，自动启用电厂安全系统和保护系统，组织应急运行，防止事故恶化。四是如果事故未能得到有效控制，启动事故处理规程，实施事故管理策略，保证安全壳不被破坏，防止放射性物质外泄。五是在极端情况下，如果以上各道防线均告失效，立即进行场外应急响应行动，努力减轻事故对公众和环境的影响。同时，设置多道实体屏障，确保层层设防，防止和控制放射性物质释入环境。

By referring the advanced international standards and drawing on worldwide mature experience, China has defined working measures to control, mitigate and cope with nuclear accidents commensurate with its national conditions and actual situation of nuclear energy development.

Implementing the defense-in-depth concept. Five lines of defense have been set up under which the nuclear emergency preparedness threshold is moved ahead and multiple barriers are installed to strengthen nuclear safety, prevent accidents and mitigate the consequences of an accident. The five lines of defense are: First, the quality of design, manufacturing, construction and operation shall be assured to prevent deviation from normal operation; second, operation procedures and operation technical specifications shall be rigorously followed and observed to ensure that each nuclear generating unit is operated within the defined safety range, any deviations therefrom are detected and corrected in a timely manner, and any abnormal operation is controlled to prevent it from evolving into an accident; third, in case a deviation fails to be corrected in a timely manner, plant safety and protection systems shall be automatically activated upon occurrence of an accident within the design datum, and emergency operations shall be organized to prevent the situation deteriorating; fourth, in case an accident fails to be controlled effectively, accident handling procedures shall be activated with the accident management strategy enforced to ensure that the containment shall remain intact and no radioactive substances are released into the environment; and fifth, in the event of failure of the above-mentioned lines of defense, off-site emergency actions shall be immediately activated in an effort to minimize any impact from the accident on the public or the environment. Meanwhile, multiple physical barriers shall be set up to ensure that multiple lines of defense are in place to prevent and control release of radioactive substances into the environment.
